Thus, owing to being provided with the transmission data area being allocated between each device respectively in each common storage and receiving data area, send the data to the common storage in all devices by scan transfer, therefore, it is possible to share identical data between each device.
Fig. 3 indicates that the figure of the structure of the transacter 41 that the data gathering system 1 of embodiments of the present invention 1 possesses.It addition, transacter 41～43 has identical structure, therefore illustrate for transacter 41 below.
As it is shown on figure 3, transacter 41 includes first network interface card the 411, second storage part the 412, second network interface card 413 and CPU414, it is connected via bus 417 respectively.

Thus, by storing the transmission speed characteristic based on the size corresponding to data in the second storage part 412 and predetermined collection team mode, little group selection portion 414a can select based on this collection team mode, using as the group of collection.Thus, little group selection portion 414a based on the transmission speed characteristic of the size corresponding to data, can select the more than one sub-group after segmentation namely to collect group as the unit reading data in group continuously, so that the reading speed of data will not decline.
The plan generating unit 414b returning to Fig. 5, CPU414 calculates the most appropriate plan (step S105).Specifically, the plan generating unit 414b number based on the sub-group selected as collection group by little group selection portion 414a and the collection cycle of collection data, generate time per unit (being set to 1 millisecond here) from the first storage part 411b, read the plan of data.
Such as, the value that plan generating unit 414b obtains divided by collecting collection cycle of data based on the number collecting group selected by little group selection portion 414a, the number of the collection group of time per unit in the collection cycle is determined with integer value.Then, generating unit 414b is by configuring this value determined at time per unit in plan, generates plan.
Fig. 7 indicates that the figure of an example of the plan generating unit 414b possessed by the transacter 41 of the data gathering system 1 of embodiments of the present invention 1 plan generated.It addition, there are high speed, middling speed, three kinds of collection cycles of low speed here, collection cycle when collecting at a high speed is 2 milliseconds, and collection cycle when middling speed is collected is 25 milliseconds, and collection cycle when low speed is collected is 200 milliseconds.Additionally, here the collection group number selected by little group selection portion 414a is set to 114, collection group number when collecting at a high speed is set to " 19 ", and collection group number when middling speed is collected is set to " 55 ", and collection group number when low speed is collected is set to " 40 ".
When collecting at a high speed, plan generating unit 414b is by collection cycle (=2) divided by collection data of collection group number (=19) that selected by little group selection portion 414a, calculating obtains " 9.5 ", therefore, the number collecting group of time per unit in the collection cycle is set as integer value by plan generating unit 414b, so that it is determined that be 10,9.
In the example shown in Fig. 7, the number collecting group of time per unit in the time 1 is configured to " 10 " by plan generating unit 414b, and the number collecting group of time per unit in next unit interval and time 2 is configured to " 29 ".In time after this similarly, the number collecting group of time per unit in the time 3 is configured to " 10 " by plan generating unit 414b, and the number collecting group of time per unit in next unit interval and time 4 is configured to " 9 ".
In addition, when middling speed is collected, plan generating unit 414b is by collection cycle (=25) divided by collection data of collection group number (=55) that selected by little group selection portion 414a, calculating obtains " 2.2 ", it has therefore been proposed to generating unit 414b is with the number collecting group of time per unit in the collection cycle that integer value is determined for " 3 " or " 2 ".
Such as, plan generating unit 414b will be set as " 3 " from the number collecting group of 5 unit interval of initial beginning, the number collecting group of ensuing 20 unit interval is set as " 2 ", so that it is determined that the number collecting group of time per unit is 3,3,3,3,3,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2.
In the example shown in Fig. 7, the number collecting group of time per unit in the time 1～5 is configured to " 3 " by plan generating unit 414b, and the number collecting group of time per unit in ensuing unit interval and time 6～25 is configured to " 2 ".In time after this similarly, the number collecting group of time per unit in time 26～30 is configured to " 3 " by plan generating unit 414b, and the number collecting group of time per unit in ensuing unit interval and time 31～50 is configured to " 2 ".
In addition, when low speed is collected, plan generating unit 414b is by collection cycle (=200) divided by collection data of collection group number (=40) that selected by little group selection portion 414a, calculating obtains " 0.2 ", it has therefore been proposed to generating unit 414b is with the number collecting group of time per unit in the collection cycle that integer value is determined for " 1 " or " 0 ".
Such as, plan generating unit 414b will be defined as " 1 " from the number collecting group in 40 unit interval of initial beginning, and the number collecting group in following 160 unit interval is defined as " 0 ".
In the example shown in Fig. 7, the number collecting group of time per unit in the time 1～40 is configured to " 1 " by plan generating unit 414b, and the number collecting group of time per unit in ensuing unit interval and time 41～200 is configured to " 0 ".In time after this similarly, the number collecting group of time per unit in time 201～240 is configured to " 1 " by plan generating unit 414b, and the number collecting group of time per unit in ensuing unit interval and time 241～400 is configured to " 0 ".
Thus, plan generating unit 414b based on the number of the sub-group selected as collection group by little group selection portion 414a and the collection cycle collecting data, generate time per unit from the first storage part 411b, read the plan of data.
Return to the Time Calculation portion 414c of Fig. 5, CPU414 based on the plan generated by plan generating unit 414b, calculate time per unit and read the time required for data, as required reading time (step S107).Specifically, the collection group number of the time per unit in the works generated by plan generating unit 414b is set to Cg by Time Calculation portion 414c, would correspond to the data transmission bauds of volume of transmitted data and be set to Vt, use following (mathematical expression 1) to calculate the required reading time Tt corresponding with volume of transmitted data.
Tt=Cg × Vt (mathematical expression 1)
Here, owing to data transmission bauds Vt is different because of the difference of the transmission speed characteristic etc. of network interface card, therefore Time Calculation portion 414c measures the data transmission bauds Vt of each collection group number by reading virtual data.Such as, if the data transmission bauds when reading the data of 4096 bytes is 25 microseconds, then the group of collection number is that data transmission bauds Vt when 4 is set to 25 microseconds by Time Calculation portion 414c.If the data transmission bauds when reading the data of 3072 bytes is 24 microseconds, then the group of collection number is that data transmission bauds Vt when 3 is set to 24 microseconds by Time Calculation portion 414c.If the data transmission bauds when reading the data of 2048 bytes is 22 microseconds, then the group of collection number is that data transmission bauds Vt when 2 is set to 22 microseconds by Time Calculation portion 414c.If the data transmission bauds when reading the data of 1024 bytes is 20 microseconds, then the group of collection number is that data transmission bauds Vt when 1 is set to 20 microseconds by Time Calculation portion 414c.
Then, in the example shown in Fig. 7, when collecting at a high speed, the collection group number read in the time 1 is " 10 ", if the collection group number wherein reading the data of 4096 bytes is " 4 ", the collection group number reading the data of 3072 bytes is " 3 ", the collection group number reading the data of 2048 bytes is " 2 ", the collection group number reading the data of 1028 bytes is " 1 ", then Time Calculation portion 414c utilizes (mathematical expression 1) to calculate the required reading time Th collected at a high speed, it is 236 microseconds (=25 × 4+24 × 3+22 × 2+20 × 1).
In addition, in the example shown in Fig. 7, when middling speed is collected, the collection group number read in the time 1 is " 3 ", if these collection groups are all set to read the collection group of the data of 4096 bytes, then Time Calculation portion 414c utilizes (mathematical expression 1) to calculate the required reading time Tm that middling speed is collected, and is 75 microseconds (=25 × 3).And, in the example shown in Fig. 7, when low speed is collected, the collection group number read in the time 1 is " 3 ", if these collection groups are all set to read the collection group of the data of 4096 bytes, then Time Calculation portion 414c utilizes (mathematical expression 1) to calculate the required reading time Tl that low speed is collected, and is 25 microseconds (=25 × 1).
Then, required reading time Tt (Th, Tm, Tl) that respective volume of transmitted data when collecting according to collection at a high speed, middling speed collection, low speed is obtained by Time Calculation portion 414c adds up to, thus calculating required reading time T is 336 microseconds (=236+75+25).
Returning to Fig. 5, then, the detection unit 414d of CPU414, based on the required reading time T calculated by Time Calculation portion 414c, judges (step S109) to whether reading out data within the unit interval.Specifically, it is determined that whether the 414d required reading time T to being calculated by Time Calculation portion 414c in portion is at threshold time judgement carried out above (step S109).Here, threshold time Tb refers to the time deducting the time margin Tc of regulation from the unit interval and obtain.Here, if 1 millisecond will be set to the unit interval, time margin Tc is set to 100 microseconds, then threshold time Tb is 900 microseconds.
In the example shown in Fig. 7, owing to reading time T required in the time 1 is 336 microseconds, below threshold time Tb i.e. 900 microseconds, therefore, it is determined that portion 414d is judged to can read out data within the unit interval.
In step S109, in the situation (no situation) being judged in the unit interval cannot to read out data, it is determined that portion 414d sends the alarm (step S111) that cannot be carried out data collection.Specifically, it is determined that portion 414d sends the alarm signal that cannot be carried out data collection to monitoring arrangement 62, and monitoring arrangement 62 shows alarm on display device 61, and exports alarm tone.
On the other hand, in step S109, under being judged to the situation (situation being) that can read data, it is determined that portion 414d carries out carry calculation (step S113).Specifically, it is determined that portion 414d, by deducting the required reading time from threshold time, calculates surplus capacity.Such as, in the example shown in Fig. 7, owing to threshold time Tb is 900 microseconds, required reading time T is 336 microseconds, therefore, it is determined that it is 564 microseconds that portion 414d calculates surplus capacity.
It is determined that portion 414d is to whether load judges (step S115) in allowed band.Specifically, it is determined that the surplus capacity that portion 414d calculates in step S113 on the occasion of time, it is determined that for load in allowed band, when the surplus capacity calculated in step S113 is below 0 microsecond, it is determined that exceed allowed band for load.
In step sl 15, under being judged to the situation (no situation) that load exceedes allowed band, it is determined that portion 414d sends overladen alarm (step S117).Specifically, it is determined that portion 414d sends overladen alarm signal to monitoring arrangement 62, monitoring arrangement 62 shows alarm on display device 61, and exports alarm tone.
On the other hand, in step sl 15, under being judged to load situation (situation being) in allowed band, digital independent portion 414e starts to collect data (step S119).Specifically, digital independent portion 414e is based on the plan generated by plan generating unit 414b, from the first storage part 411b, read data, then the moment obtained by timer 411a timing is set up with the data read out and associate, and store in the second storage part 412 as process data.
As it has been described above, the transacter 41 that data gathering system 1 according to embodiment 1 of the present invention possesses, including: the first storage part 411b, this first storage part 411b are stored between multiple control device 21～23 data of scan transfer；Little group selection portion 414a, the memory area of the first storage part 411b is divided into multiple group by this little group selection portion 414a, and the memory area of group is further divided into Duo Gezi group, data transmission bauds characteristic based on the size corresponding to data, the more than one sub-group after segmentation is selected namely to collect group as the unit reading data in group continuously, so that the reading speed of data will not decline；Plan generating unit 414b, this plan generating unit 414b number based on the sub-group selected as collection group and the collection cycle of collection data, generate time per unit from the first storage part 411b, read the plan of data；And digital independent portion 414e, this digital independent portion 414e are based on the plan generated, from the first storage part 411b, read data, therefore no matter data volume number equal can promptly collect data with simple structure.
Fig. 8 indicates that in the transacter 41 that the data gathering system 1 of embodiments of the present invention 1 possesses, the flow chart of the process step of the process when the project of newly-increased collection data.
As shown in Figure 8, if increased newly the project (step S201) collecting data by user operation, then whether the data of the plan generating unit 414b data items to increasing are included in collection group and judge (step S203).
In step s 201, under being judged to the situation (situation being) that the data of the data items increased are included in collection group, the data of the data items owing to increasing have become as the object of data collection, and therefore plan generating unit 414b adds this data items in collection group (step S205).
On the other hand, in step s 201, under being judged to the situation (no situation) that the data of the data items increased are not comprised in collection group, the data of the data items owing to increasing are not the objects of data collection, it is therefore desirable to regenerate plan.
It has therefore been proposed to this data items is added in the time that collection group number is minimum (step S207) by generating unit 414b.In the example shown in Fig. 7, when the data in increasing the collection group as collection at a high speed that is not included in, plan generating unit 414b collects the collection group that in group's number minimum time and time 2, interpolation comprises newly-increased data items in time 1 and time 2, and from " 9 ", collection group number is changed to " 10 ".Similarly, the collection group number in the time 4,6,8 is changed to " 10 " from " 9 " by plan generating unit 414b similarly.
Thus, plan generating unit 414b generates plan again, so that reading out requested data from the first storage part 411b in the number of collecting group within the unit interval minimum time period.Thus, when increasing, in the process of data collection, the data items adopted, no matter data volume number, also all can promptly collect data with simple structure.
It addition, in embodiments of the present invention 1, transacter 41 is based on the collection team mode shown in Fig. 6, and group selects to collection, but collects team mode and be not limited to the pattern shown in Fig. 6.
